F. CANNON -GEYSER OR LIKE WATER HEATER Filed May 24, 1928 2 Sheets-Sheet2 wards.

Patented Jan. 21, 1930 UNITED STATES PATENT OFFICE GEYSER R LIKE WATERHEATER Application filed May 24, 1928, Serial No. 280,2?6, and in GreatBritain June 1, 1927.

This invention relates to geysers and like water heaters of the class inwhich a number of angled trays are fitted inside of a casing one overthe other, the top one of which is supplied with cold water from a pipethe water flowing from each tray in succession, the products ofcombustion from a burner at the base flowing upwards between the traysto the outlet for heating the water.

The object 01 this invention is to construct such apparatus in animproved manner and in which the trays rest upon one another, themajority of them being made alike, whereby all as also the water supplypipe and the gas burners, are removable or replaceable without it beingnecessary to employ skilled workmen in making up or repairing a geyser.

My invention will be clearly understood from the following descriptionaided by the annexed drawings in which Figure 1 is a part sectionalfront view, the door of the casing being removed; Figure 2 is a sideview of the geyser; Figure 3 is a plan view, Figure 4a a section on theline 4-4 of Figure 1 and Figure 5 is a section on the line of Figure 1.Figure 6 is an enlarged section of the Water pipe connection.

According to this invention I take an open tube to form a casing 1, sayoblong in cross section and open at top and bottom and the front Iconstruct removable or as a door 2, the casing 1 and door 2 beingsuitably packed it required to conserve heat.

The bottom of the casing rests upon or is provided with feet at and theside walls at the bottom are provided with holes or openings 5, thefront at the bottom being provided with a hinged door 6 preferablyperforated at its lowest part.

At the back and sides inside the casing 1 I position a shelf or flange 7just above the openportions 5 andthis shelf carriesa shallow tank 9constructed with a depending narrow channel 9, the outer walls of whichform the side walls of the tank and extend to the top thereof where theedges 32 are turned in- By this means an inverted bottom 9 for the tank9 is formed, and therein is provided a hole having an upstanding wall 38as an outlet for the gases whilst a curved wall 37 is positioned on thebottom 9 to act as a weir to prevent a direct flow of the water to thepipe 10.

To the base of this tank 9 and extending through the base near itscenter I position a depending tube 10 which has a right angled extension10 to which is screwed one end of a delivery spout 10 which projectsthrough a hole in the side of the casing 1 to outside thereof as atFigure 1.

I construct a gas burner 12 preferably two armed and I connect same to aplate 13 with the tap 14 and gas pipe connection 14 on the opposite sideto the burner and this burner 12 I position under the tank 9 with oneend resting on a bar 15 positioned across the easing with the plate 13engaging hooks 11 projecting from the feet or lower side of the easingso that such burner 12 can be easily positioned and removed.

I construct a number of shallow trays 16, 17, 18, 19 of a size to fitthe casing loosely, each tray having a turned in edge 32 at the top andwalled or sleeved opening 33 at the bottom, the sleeve in each caseprojecting above the bottom of the tray so as to form a weir.

I employ a number of these trays and position them one above the otherwith their openings 33 alternatively arranged, the bottom one resting onthe turned in edge 32 of the tank 9 while the others rest upon oneanother.

In the top of the casing I position a shallow vessel or tray 23 and restsame on the turned in edge 32 of the uppermost tray 19, and such vessel23 has a central chimney 25 and a spout 26 near one end and on thisvessel 23 I position a cover 27 having a cone shaped funnel 28 and alsoa hole for encircling the chimney 25.

The water supply pipe 29 is supplied with clips 29 having hooks 29 forbeing connected to ledges or loops 30 on the outside of the casing 1 aswill be understood from Figures 1, 2, 4 and 6, and such supply pipe 29has a curved top for leading the water into the tunnel 28 whilst thelower part is provided with detachable means 31 for connection to thewater supply main.

On closing or afliXing the door 2 and posit-inning the cover 27 the tank9 and trays 16, 17, 18, 19, 23 are completely enclosed.

Thus it will be seen that the cover 27 and top vessel 23 and the watersupply pipe 29 can be easily removed and on opening or removing the door2 the trays 16, 17, 18, 19 can be readily removed, and on disconnectingby unscrewing the outlet pipe 1O from the tank 9, both can be readilyremoved as also can the gas burner 12, by lifting it with the plate 13ofi the hooks or engaging means 11.

In operation the water flows from the supply pipe 29 into the funnel 28from which it passes into the vessel 23 to the spout 26 where it assesinto the top tray 19 and passes along same to its opening 33 to fallinto the next tray 18 and so on through the series of trays to the tank9 where it passes to the outlet pipe 10 the water passing along eachtray and the tank in film form, and the top of each spout projectingabove the bottom of the vessel, trays and tank, water will be held infilm form, the upwardly projecting portions of the walls 33 and theprojecting top of the pipe 1O acting as weirs.

The heat from the gas acts firstly upon the bottom of the tank 9 andthen passes through the opening or" the wall 38 and up to under thebottom tray 16, passing through the walled opening 33 and then to thenext tray 17 and through the opening in its wall 33 and so on betweenand through the series of trays in azigzag manner to the vessel 23 atthe top, where it passes to the chimney 25, thus heating the water inthe tank, trays and vessel during its progress.

If the case is complete, i. e. without a door, the tank and trays may bedropped in or removed trom the top, the tank resting on a ledge with thetrays resting on one another and the top vessel or cover may beafterwards connected.

lVhere gas is not available an oil lamp may be employed instead of thegas burner.

lVhat I do claim as my invention and desire to secure by Letters Patentis 1. A eyser comprising a vertical casing having openings at the base,shelves within the casing adjacent the base, a tank having a dependingnarrow channel around same, and having a hole in the bottom, a sleevefitting in said hole and extending above the bottom, an outlet pipeconnection from the bottom of the tank, an inturned edge at top of tank,a weir carried upon the upper side of and across the tank, the tankresting on said shelves in the casing, a series of trays each having aninturned upper edge and provided with a hole in the bottom, a sleevemounted in said hole and extending upon both sides of the bottom, thetrays being positionable within the casing and resting one upon theother and on the tank with the sleeves alternately arranged, a shallowves- 'sel positionable on the top tray and within the casing and havinga central chimney, a spout and an inturned upper edge, a removable coverfor the casing having a hole embracing the chimney of the shallowvessel, and a funnel, mounted in the cover and emptying into the shallowtray.

A water heater including an open ended casing, a plurality of inwardlyprojecting flanges carried by the casing and adjacent to the bottomthereof, a lid for the top of the casing and having a flue opening andwater inlet, and a water and heat conducting member mounted in thecasing from the top end thereof andresting upon the flanges, said membercomprising a lower tank provided with an inverted portion in its bottomforming a heating chamber with an outlet below the upper edge of thetank, an upper tray having a central flue projecting through the flueopening of the lid and with an inturned rim terminating short of the topof the flue, and a plurality of intermediate trays resting one upon theother and on the tank, and supporting the upper tray, each of saidintermediate trays being provided with a water outlet, and a sleevedisposed in each outlet and projecting above and below the bottom of itsrespective tray to form means to regulate the depth of the water film inits respective tray and also a by-pass for the gas.

In testimony whereof I have hereunto set my hand.

FREDERICK CANNON.
